EMWaver

EMWaver: Your Personal Lab for Sub-GHz, Infrared, BLE, and USB Signal Exploration

EMWaver is an educational electronics platform built around the ESP32-S3, designed for learning and experimenting with wireless communication, automation, and embedded hardware.

Connect to the EMWaver board instantly — no manual pairing or setup required. The mobile app gives you full control of the hardware, offering a smooth and engaging experience whether you're learning, prototyping, or building custom tools.

Key Features:
Sub-GHz Communication with CC1101
Transmit and receive signals in popular Sub-GHz bands using the onboard CC1101 module. Capture raw waveforms, visualize signal patterns, and develop wireless communication prototypes.

Infrared Learning and Playback
Record IR signals from remotes or import codes from IRDB. Transmit and replay them easily using built-in tools.

Real-Time Signal Sampler
Monitor incoming waveforms in real time from Sub-GHz, infrared, or any connected GPIO pin. Ideal for learning signal behavior or debugging hardware.

JavaScript Console for Hardware Control
Interact with EMWaver using a built-in JavaScript console. Control GPIO pins, trigger transmissions, and automate sequences — all within a restricted, sandboxed scripting environment.

Plug-and-Play Module Support
Easily connect modules like MFRC522 (NFC), nRF24 (2.4GHz), or your own custom hardware via GPIO headers — no soldering required.

USB HID Emulation
EMWaver can emulate standard USB HID devices such as keyboards and mice, enabling remote automation and input simulation from the app.

EMWaver is open source, educational, and built to grow with you — from signal exploration to full embedded systems development.
